open source systems for libraries

Four from OCLC

Peter Binkley wrote in to oss4lib-discuss about OCLC's Software page, listing four open source efforts from their Office of Research. They are ALCME, the Advanced Library Collection Management Environment, for OAI-compliant collections; Pears, a text storage and indexing system; GWEN, a database search engine with an interface to Pears, and dbutils, utilities for database programming.

Nice to see OCLC stepping up to the plate; all code is apparently available from cvs, and their license, while requiring modifiers to contribute code, appears reasonable (though ianal).
